hi.

i wan to knw abt capacitor.

so, if brand new capacitor, so is empty lo.

thn can direct join the main power cable ?

but i seen some info, not allow to join direct main power cable to capacitor.

must charging thn only join power cable oh.


capacitor 20f


capacitor 35f


capacitor 4.0f


capacitor 8.0f


i found an url ..
cap charging step.

some come already charged, so just follow the instruction manual...

yeah follow instruction manual...

if said so, do lah...if not, just PnP lah

Hi bros, i was wondering..i have 2 units of tiny puny Helix Cap 33 connected to HU..i have not driven my car for almost 4 days, today i checked my battery voltage at terminals was 12.3V (engine off)..i remembered b4 on Monday was around 12.6V (engine off)..

is it true that the 2 Helix Cap 33 drained my battery, or is it my car alarm (currently using Steelmate 898G)? how bout u guys who have installed much bigger farad capacitor, experienced faster battery drain??

I have 2 biji 1F and 8biji headcaps. Have left my car unstarted for 2 weeks with no problems. Cheap Yoko battery.
I think you're being a bit too Volt sensitive.

Lol... 0.3 diff is really nothing... Unless u said the reading was like 10v

hehe..yea, i just want to make sure everything is problem free..but then, how many years could a cap become bad? sometimes bad cap could actually drain battery charge rite?

but when i turn my key to ACC-ON (engine not running), i went to check the voltage it became from 12.3V drop to 11.7V, i dunno if this is normal...however no problem start the engine lah, 1 fast crank can dy..

sori 2 hijack this thread, but i wanna ask sumthin bout caps too.. is it ok 2 disconnect ur batt terminal when u have caps installed, say bout 2-3 weeks??

when connect back, use a resistor to slowly charge up then only connect back ur +ve batt terminals. this will prevent arcing!

im sori 2 ask this, but wats a resistor?? new 2 caps, was advised 2 install one by my ICE installer

when u turn to ign on, some electrical are running...ur ecu, tcu, bcm, sensors and ignition coil, meter lights..etc....they draw currents.

as long as ur battery is >12 when not in use, and >13.5 after start, ur system is still ok...

Added on October 31, 2011, 2:20 pmu need a multimeter with capacitance reading to know whether a cap is good or bad. :>
